Bottleneck on GTX 670 on PCI Express 2.0?

[paperrockbazooka]

Thanks for reading, your assistance is much appreciated! Buying this PSU and GPU...

GPU: Gigabyte Nvidia gtx 670 http://www.newegg.com/Product/Product.aspx?Item=N82E16814125423
PSU: Antec 750W High Current Gamer Series http://www.newegg.com/Product/Product.aspx?Item=N82E16817371049


...to add onto my old setup listed below. Goal is to play Witcher 2 on highest settings. I think CPU will hold up fine. Might get 4 gbs of ddr2 ram to add onto build-- not sure more ram is necessary though. Mostly concerned with my mobo as I know it will bottleneck performance of gpu somewhat, but unsure as to what degree (PCI Express 2.0).


Mobo: ASUS P5Q Pro LGA 775 Intel P45 ATX Intel Motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E16813131299
CPU: Intel Core 2 Quad Q6600 Quad-Core Processor http://www.amazon.com/Intel-Q6600-Q...ve=165953&creativeASIN=B000LRMR26?afsrc=fstfx
RAM: CORSAIR XMS2 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 http://www.newegg.com/Product/Product.aspx?Item=N82E16820145184

You've also said a few dual core will handle too aahhh i can't seem any dual core which provding a complete power to gtx 670 or 680 first you'll show some proof then i'll show you a dozen..

i know i should just leave it alone BUT
Test System And Benchmarks
AMD Radeon HD 7970 (about the same league as a 670/680 right?)

but yes this is a bottleneck

however don't think a dual core can't do it, not the most desirable, but it games with a high end card
. .feh.

lets provide some proof so to better educate me than give an opinion please

I can attest to the fact that a q6600 even at 3.2Ghz can be a serious bottleneck for a gtx670, because thats what i had up until this past thursday. I too was convinced by 99% gpu utilization in BF3 ultra 1920x1200 sp; 99% utilization in Saints Row 3 and others. These games stayed above 60fps. But crysis 1 still struggled to go past 20's fps in some places; gothic 4 stuggled to keep above 30 fps. And risen 2 fluctuated in the 20s as well. These games ran around or below half utilization of the gtx 670.

i was sorta mixed about the 6600. this thing was legendary for me. 5 years pretty much to the day and 5 Gfx cards later most stuff was smooth or super smooth. So i so wanted to stretch that CPU to the 7 year mark. That would have been awesome. However the upgrade bug hit me.

So i had a new rig slappd together with a i7-3770@ 4.5Ghz. Crysis 1 now runs 60+ fps everywhere - no dips at all. rather than dips into the mid and low 20's at times. Impressive running high settings on single GPU at that speed. Gothic 4 runs more than 2 x the speed with 60+ fps. And Risen 2 i have yet to test as im on vacation . But the point here is i had 99% utilization on the card withh a smoking new cpu.

Moral of the story is : if your game rig runs a game at 99% utilization be happy with your q6600. if not you are missing out. that is irrefutable. and the proof i think you are asking for looniam.

and the proof i think you are asking for looniam.

i appreciate your response though the games you gave "testimony" to struggling, struggled under any set up with the way they were poorly ported. they were not used for any benchmarking in reviews on sites with crysis being the exception for a short time just for that reason. upgrading to a i7-3770 @ 4.5 would provide a serious difference in performance.

i am still waiting to hear the B.S talkers back up what they stated; the dozen benchmarks for every one i provided. even the second bench i posted help their cause but you think they understand that?

bottom line. you CAN run into one component restricting another under certain circumstances . . that doesn't mean it bottlenecks in all situations.

Aye Looniam, I too have seen benches that make zero difference to what quad core you are running. The heaven 3.0 benchmark is an example. Makes not one iota difference with an OC Q6600. I would have to say if theres a game you end up dissatified with, you can mothball it Plenty of good stuff that isn't running slow on a q6600 and a gtx 670 by a long shot.

PaperRockBazooka I hope you stretch that q6600 few more years ! I speak with my local computer store techs and they love that CPU as well. Prob one of the best ever. It was good for me even with a stock cooler it never complained !
